when there is none to find but get real. If you spend 2 hours sitting in an uncomfortable and flooded locker room while your opponent sits in comfort with their Xbox, leather lined recliner, etc. it makes a difference when you get back on the field. So in that sense yes - a large part of the game did take place in the locker room.
It is laughable all the clowns that pretend that the situation was the same for both teams.
